A simple gas sensor system applicable for monitoring various environmentally deteriorating gases was fabricated by the combination of a newly developed cerium ion conducting solid electrolyte, (Ce_xZr_1-x)_4/(4-x)Nb(PO₄)₃, and yttria stabilized zirconia (YSZ). By applying the oxycarbonate or the potassium nitrite mixed gadolinium oxide based solid solution as an auxiliary electrode, the sensor can detect CO₂ gas or NO gas, respectively, with demonstrating a rapid, continuous, and reproducible response, which obeys the theoretical Nernst relationship. The present sensor fabrication proposes the approaches to pursue for detecting various gases only by exchanging the auxiliary electrode suitable for the target gas sensing.
